After suffering a rare illness, straight-A student Cara Scotto struggles to deal with lingering side effects. Refusing to admit she can't handle the disruptions in her otherwise normal life, she tries to move on and heal.

Alexander DeMarsh is unhappy about returning to his small hometown for three weeks. He prefers living in the city, where he attends an elite boarding school far away from his overprotective parents. Sure, they have reason to worry about him. As a Generator, Alex's body constantly manufactures supernatural energy that's often difficult to control.

Over winter break, Alex runs into Cara and picks up on the powers they share. Soon, he realizes Cara is the only person in the world who has any chance of understanding him. But first, he needs to find a way to draw out her supernatural abilities without revealing too many secrets of his own.
